HSPI not working on ESP_LAUNCHER dev board

Hello, I have some experience with ESP-01 and ESP-03 modules. I have written some C code on it, using the Arduino adaptation layer. With this code, I got an application that uses the HSPI port of the ESP8266EX to connect to a SPI accelerometer (ADXL362). My problem is that the same application does ...

This is a major feature whenever we speak of IoT, because nowadays, IoT platforms are often battery-powered and th...

Re: Wake up interrupt from deep sleep

What is the way to enter the light-sleep state ?
I only saw a deep_sleep() API in the documentation.
